2 Claims.

This invention relate s'to improvements in hair curling clamps and rods, more particularly to such devices employed in.what is known as the Croquignole waving of hair wherein the hair strands are wound on a rod and held by a clamp preliminary to the application of a heating medium thereto, and the instant application is a division of an application filed December 6, 1938, serially numbered 244,185.

It is among the objects of the invention to provide improved means for locking the curling rod to the protector clamps when winding of the hair thereon has been completed.

A further object of the invention is the provision of a curling rod having an external ratchet at one end thereof and a spring biasing means at the opposite end whereby the ratchet teeth coact with a rigid pawl provided on the protector clamp.

Still a further object of the invention is the provision of a curler rod and protector clamp in combination which shall be of durable and economical construction and which shall be free from clogging by foreign particles.

These and other objects of the invention will become more apparent from a description of the accompanying drawing constituting a part hereof in which like reference characters designate like parts and in which:

Fig. 1 is a top plan view of a protector clamp in the open position;

Fig. 2 a top plan view of the assembled protector clamp and curler rod embodying the principles of this invention;

Fig. 3 a vertical cross-sectional view of the curler rod taken longitudinally along the lines 3-3, Fig. 2;

Fig. 4 a transverse cross-sectional view of the clamp and rod taken along the line 4-4, Fig. 3; and

Fig. 5 an end elevational view of the curler rod.

With reference to the several figures of the drawing, the structures therein illustrated comprise a clamp constituted by the hinged jaws I and 2 pivoted at 3 and provided with a lock lever 4 that constitutes no part of the present invention, the clamp in its closed position having lever 4 lying adjacent one side as shown in Fig. 2.

The numeral 5 generally designates the curling rod which is adapted to be mounted on end brackets 6 and 'l of the protector clamp, the rod being so mounted by journals 8 and 9.

Both ends of the rod 5 are recessed at l0 and 55 October H, the recess I0 being of square shape to receive a winding key by which suitable tension is applied to the hair strands after they are wound on the rod. The recess l I which is counterbored as shown is adapted to receive the journal pin 8 and a coil spring I2, the latter abutting one wall of the recess H and the shoulder on the journal pin 8, whereby the latter is normally biased outwardly from the curling rod I I to seal the recess II and prevent treating fluid and grit or hair from clogging the recess and working parts. The end of the rod opposite the resiliently mounted journal pin 8 is provided with a ratchet toothed face 13 which interacts with a stationary pawl l4 clearly shown in Fig. 1 of the drawing, the biasing pin 8 forcing the curler rod 5 against the pawl 14 with teeth l3 at all times in engagement therewith.

The two hinged sections of the clamp are provided with a peripheral upstanding wall constituting the end brackets 6 and l for mounting the curler rod 5 and also serving as a housing to hold flexible pads in'position after the hair is wound on the rod. As shown in Figs.'3 and 4, the wall portion is essentially of a height beyond the center of the curler rod, and as shown in Fig. 3 extends above the rod in the constricted center portion thereof. As a result the pads, such as the chemical heater pads, when used, are retained between the upright walls and the walls also function to reflect the heat to the center of the curler rod and away from the adjacent portion of the scalp.

In the operation of the above described curler rod and protector clamp, the latter is clamped with its faces engaging strands of the hair that have been separated to be curled, the clamp being placed adjacent the skull with a protecting felt therebeneath. The ends of the separated hair strands are then wound around the curler rod which is engaged at its ends by the operator who continues turning th rod to wind the hair while bringing the rod nearer the clamp and when it is all wound the rod is snapped in the brackets 6 and l of the protector clamp as shown in Figs. 2 to 4 of the drawing. The key for winding the rod to apply the necessary tension to the hair strands is then inserted in the recess I0 and the rod is wound while in the protector clamp journals to impose the desired tension upon the hair strands, and the pawl M will hold the rod 5 in any angular position against the tension of the hair strands. Suitable heating means is then applied either by th so-called heatless pad method or electrical resistance or steam heating methods or in any other suitable manner to permanize the strain imposed upon the hair by the curling action.

It is evident from the foregoing description of this invention that the provision of the ratchet teeth on the end face of the rod with the spring biased journal pin at the opposite ends is a positive means of applying and maintaining the necessary tension on the hair strands and a convenient means of winding the hair after it has been curled on the rod element.

The accessibility of the teeth permits keeping them clear from foreign matter so as to avoid interference with their proper function as in other types of ratchet devices heretofore in use, particularly those obtained with the curler rod. The spring biasing means employed provides a rugged and inexpensive construction which is not subjected to failure through breakage or distortion.

Although one embodiment of the invention has been herein illustrated and described, it will be evident to those skilled in th art that various modifications may be made in the details of con struction without departing from the principles herein set forth. 1

I claim:

1. In an apparatus for permanent waving of hair, a divided clamp for engaging strands of hair comprising two sheet metal members each having a base, an uprising side and ends continuous with each other, said members being adapted when brought edge to edge to form a complete enclosure on its bottom, sides and ends and serving to hold flexible pads in position and further functioning to protect the scalp from the heat generated around said pad, said ends serving as end brackets for supporting the curler rod in the clamp, said side and end walls extending abovethe normal axis of the curler rod when mounted in the clamp.

2. In an apparatus for permanent waving of hair, a divided clamp for engaging strands of hair comprising two sheet metal members, each having a base, an uprising side and ends integral and continuous with each other, said members being adapted when brought edge to edge to form a complete enclosur on its bottom, sides and ends and serving to hold flexible pads in position and further functioning to protect the scalp from the heat generated around said pad, said uprising ends constituting end brackets for supporting a-hair curler rod, and said sides and ends forming a continuous uninterrupted retaining wall around the periphery of the clamp.
